Setup and Installation
Proper installation is crucial for the performance and longevity of your ice maker. Follow these steps carefully:
Unpacking and Placement
- Remove all packaging materials, including tape and foam.
- Inspect the unit for any shipping damage. If damaged, contact your supplier immediately.
- Place the ice maker on a flat, stable surface capable of supporting its weight when full of ice and water.
- Ensure adequate ventilation around the unit. Maintain at least 6 inches of clearance from walls and other appliances.
- Keep the unit upright for at least 24 hours before initial operation to allow the refrigerant to settle.
Water and Drain Connections
The ice maker requires a continuous water supply and a drain connection.
- Water Inlet: Connect the provided water hose (3’28”) to a potable water supply with a 1/2-inch faucet connection interface. The machine connection interface is 3/4-inch.
- Water Filter: Install the included water filter in-line with the water supply to ensure clean water for ice production.
- Drainage: Connect the provided drain hose (2’63”) to the machine's water outlet and route it to a suitable floor drain or sink. This model supports gravity drainage. Ensure the drain hose has a continuous downward slope to prevent water backup.
Electrical Connection
- Plug the power cord into a dedicated, grounded 115 Volt electrical outlet. Do not use extension cords.

Manual Cleaning
- Exterior: Wipe the stainless steel exterior with a soft cloth and mild detergent. Avoid abrasive cleaners.
- Interior: Periodically clean the ice storage bin and interior surfaces with a solution of water and a small amount of bleach or a food-grade sanitizer. Rinse thoroughly.
- Water Filter: Replace the water filter as recommended by the manufacturer or if you notice a decrease in ice quality or production.
- Condenser Coils: Clean the condenser coils (located behind the front vents) regularly with a brush or vacuum cleaner to ensure efficient heat dissipation. Blocked coils can reduce performance.
